[0002] Most families' shower rooms are equipped with handheld showerheads. Usually, the handheld showerhead is inserted into the showerhead bracket, which is connected to the showerhead seat. The showerhead seat is installed on the vertical shower rod. The height of the showerhead can be adjusted by manually adjusting the position of the showerhead seat on the showerhead rod. When showering, the taller the person is, the higher the showerhead seat is required to be. After using the showerhead, the taller family members will place the showerhead seat in a higher position. When the shorter family members, especially children, use the showerhead, they cannot reach it and cannot directly adjust the height of the showerhead. They need to use a climbing stool, which brings great inconvenience to daily life and also brings certain safety hazards. It can be seen that there is a great demand for a showerhead seat that can conveniently adjust the height of the showerhead.

[0003] The existing devices for adjusting the height of showers mainly have the disadvantages of being too large in structure and inconvenient to install: A shower with adjustable height (CN201910494831.1), in which the shower is installed on a chain, and the height of the shower is adjusted by lifting the chain. This device can adjust the height of the shower well, but the entire chain transmission mechanism is too large, and it is not easy to install in the bathroom. A shower fixing device with adjustable height (CN201621342722.6), which uses the principle of screw-nut transmission, connects the shower seat and the nut together, and drives the screw to rotate through the bevel gear transmission to achieve the lifting of the shower seat, but the structure of the screw and the transmission device is too large, and the installation is relatively complicated.

[0024] Referring to the attached drawings, a pull-cord type lowerable shower seat includes a seat body mounted on a shower rod 13, the seat body is divided into a left seat body 1 and a right seat body 12 along the axis of the shower rod 13, the left seat body 1 and the right seat body 12 are connected by screws 5, and the outer surface of the seat body is provided with a chrome plating layer. The seat body is a hollow rectangular structure, and two groups of roller assemblies are installed in the seat body, and the two groups of roller assemblies are symmetrically arranged on the left and right sides of the shower rod. The roller assemblies can roll up and down along the outer wall of the shower rod 13, wherein the roller assembly close to the right side is also connected to a locking assembly for stopping the roller assembly from rolling relative to the shower rod 13; the components in the roller assembly and the locking assembly are made of rust-proof and corrosion-resistant materials.

[0025] The roller assembly includes two rollers 2 distributed in the up-down direction, and the outer circumference of the roller 2 is provided with an annular concave structure adapted to the wall of the shower rod 13 in the circumferential direction; in order to ensure good contact characteristics between the rolling wheel and the shower rod, the contour diameter of the rolling wheel needs to be determined according to the diameter of the shower rod; the outer side of the annular concave structure is provided with a rubber layer for increasing friction and preventing the roller assembly from sliding relative to the shower rod 13 in the stopped state; the roller 2 is fixedly mounted on the roller shaft 3, and the roller shaft 3 is supported by two bearings 4 arranged in the base body; the four rollers are arranged in a rectangular shape, and are aligned up and down and left and right respectively. The two rollers on the left and the roller on the lower right are not restricted in rotation, and the rotation of the roller on the upper right is restricted by the stop gear;

[0026] The locking assembly includes two stop gears 6, which are respectively installed at the two ends of the roller shaft located on the upper right side; the teeth of the stop gears should be slightly larger to enhance the rigidity and life of the teeth. A movable locking rod 7 arranged in the horizontal direction is provided on the right side of the stop gear 6. The movable locking rod 7 consists of a left half and a right half. The cross-sectional area of ​​the left half is larger than the cross-sectional area of ​​the right half, so that a step surface is formed between the left half and the right half; a stop tooth is provided at the left end of the movable locking rod 7, and a guide groove is provided in the left half of the movable locking rod 7 along the length direction; a connecting rod is provided at the right end of the movable locking rod 7, and the connecting rod 11 is arranged between the two movable locking rods 7 and is perpendicular to the movable locking rod 7 to ensure that the two movable locking rods act synchronously.

[0027] A guide pin 8 is provided at a position corresponding to the guide groove on the inner wall of the seat body. The guide pin 8 is placed in the guide groove of the movable lock rod 7, and the guide pin 8 and the guide groove are in sliding fit; a guide sleeve 10 is provided at a position corresponding to the right part of the movable lock rod 7 on the inner wall of the seat body. The guide sleeve 10 is made of elastic wear-resistant material. A through hole is provided on the guide sleeve 10 that passes through in the horizontal direction, and an elastic opening is provided on one side of the through hole to facilitate the installation of the movable lock rod 7. The right part of the movable lock rod 7 is movably inserted into the guide sleeve 10; a compression spring 9 is provided between the guide sleeve 10 and the left part of the movable lock rod 7. The force of the compression spring 9 should ensure that the movable lock rod 7 can be effectively reset when the external force is removed, and the stop gear 6 can be locked, but it should not be too large, otherwise a greater pulling force is required when moving downward, which may cause the instantaneous speed of the shower seat to move downward too fast.

[0028] A control rod 14 is provided on the left side of the connecting rod 11, and the control rod 14 vertically penetrates the seat body; the upper diameter of the control rod 14 is larger than the lower diameter, and the upper part of the control rod 14 is located outside the seat body; the upper part of the control rod 14 is larger than the size of the installation hole of the control rod 14 of the right seat body 12, which can limit the downward stroke of the control rod 13 within a reasonable range, and is also convenient for manual pressing operation. The lower part of the control rod 14 is provided with an inclined surface inclined to the upper right corresponding to the position of the connecting rod 11, and the inclined surface contacts the connecting rod, and the connecting rod 11 is driven by the movement of the control rod 14; when the control rod 14 is forced to move downward, the inclined surface pushes the connecting rod 11 to move rightward, so that the movable lock rod 7 is separated from the stop gear 6; when the control rod 14 is not subjected to external force, under the action of the restoring force of the compression spring 9, the movable lock rod 6 moves to the left, and the control rod 14 moves upward, so that the movable lock rod 7 is meshed with the stop gear 6. Specifically, the up and down stroke of the control rod 14 is not greater than 10 mm, and the inclined angle of the control rod 14 is not greater than 45°. The portion of the lower end of the control rod 4 extending out of the seat body is connected to the pull rope 16 through the connecting pin 15.

[0029] Key dimension control requirements: the stroke of the connecting rod 11 under the push of the control rod 14 must be greater than the size of the engaging part of the stop gear 6 and the movable locking rod 7, ensuring that the movable locking rod 7 can be completely disengaged from the stop gear 6 when the control rod 14 is actuated; the distance between the upper end shoulder of the control rod 14 and the upper surface of the right seat body 12 must be slightly greater than the height dimension of the effective action inclined surface of the connecting rod 14, ensuring that the downward force of the control rod 14 acts directly on the right seat body 12, rather than on the connecting rod 11.

[0030] Installation process of shower seat: separate the left seat body 1 and the right seat body 12, and place them on both sides of the shower rod 13, that is, place the shower rod in the holes of the left and right seats, and connect the left and right seats together with screws 5 to complete the installation of the shower seat. The shower bracket can be installed on the shower seat through the threaded hole at the left end of the left seat body with screws.

[0031] Shower seat pull rope downward operation: when the upper end of the control rod 14 cannot be directly operated by hand, that is, it is out of reach, the pull rope 16 can be pulled downward by hand to move the shower seat downward, and the shower seat stops moving downward when the pull rope is released. This process can be repeated to safely move the shower seat downward to the target position.

[0032] The shower seat button moves up and down: when the upper end of the control rod 14 can be directly operated by hand, that is, when it is within reach, the control rod 14 can be fully pressed with a finger, and then an upward or downward force is applied to make the shower seat at a suitable height.
